To all 'whomitfmay concern: j

Be. itknown thamwe, .THOMAS R.. MURRAY, JAMES P. VMURRAY,and.EDWARD S.fNErLAN, citizens of the United States, .residingat New London, inthe.county .of `New ,London and State of .Connecticut,..have. invented newand useful Improvements .in Street-Cleaners, of which the following `isaspecitication.

This .invention -relates tosti-eet cleaners and one oftheprincipal-.objects of theinvention -is:.-to providea simple andefficient device whereby the `dirtzmay be readily removed from thestreetswthout causing any dust, such as is the case with sweepers.

A further object -of the invention is to provide a vacuum operatedstreet: cleaning device in which the exhaust in the dustchamber isconveyed directly to a hood whichincases the suction head so that.. anydust escaping from the dust chamber will be again/taken upby the suctionhead and thereby prevented from escaping.

Further objects of this invention will appear as the following specificdescription is read in connection with the accompanying drawings whichform a part of this application, and in which l Figure 1 is a sideelevation. Fig. 2 is a rear elevation. Fig. 3 is a longitudinal sectionon the line 3-3 of Fig. 2. Fig. 4 is a front elevation partly insection. Fig. 5 is a vertical section on the line 5-5 4of Fig. l.

Referring more particularly to the drawings, 1 represents the chassis ofthe ordinary motor vehicle upon which is hung the engine casing 2 havingprojecting therefrom the driving shaft 3 which is connected to thedriving wheel 4 by means of chains and sprockets 5.` The ,front wheelsare steered in the usual manner from the steering post 6 and in allother respects, the parts described are similar to an ordinary motortruck. Mounted upon the chassis is a box-like body 7 which overhangs thewheels thereof and has a door 8 hinged to one side thereof so thataccess may be had to the dust chamber 9 for removing the dust andaccumulated dirt therein. The forward portion of the body is separatedfrom the dust compartment by 'means of a par'-l tition 10 so as to forma suction compartment 11, as shown. This compartment has arrangedtherein a suitable shelf 12 upon which a suction blower 13 is mounted.The

,blower 13 is preferably'driven .by `a belted .connection 14'with acounter shaft 15 driven through .themotor by abelt and ipulley 16 .and17, the latter element. being loosely .mounted upon the counter shaftandbeing :connected .tothe shaft 15 by means of the clutch 18 Vcontrolled.by a-lever 19 vadjacent the .drivers seat 20.

The .blower is provided with an exhaust 21 and with an inlet pipe 22which extends from the back of the body through the com- .,partulent9.fto.a connection with the blower. rThe inletpipe 22 is connected toasuction .rhcad 23by.1neans of an elbow 24 anda ilexible. joint.25 .whichl,pei-mits. the raising of the suction hcad,.as.will behereinafterdescribed, so that the same may bev thrown to inoperativeposition andmay also ace commodate'its'elf tov the inaccuracies in the roadsurfaces. l

The suction head and its associated parts are arranged within a hood 26which consists of aplurality'of uprights 27 connected together byrectangular frames 28 and covered with any suitable fabric 29, such ascanvas or the like which is attached to the separate frames in anysuitable manner.

The lower frame 28 is preferably secured to f the lower end of thesuction head and the upper frame is supported upon bolts 3() adjustablycarried in brackets or arms 31 and having compression springs 32surrounding the same between the frame and the bracket arms. Thesesprings permit the raising and lowering of the hood so as to accommodateitself to the inaccuracies in the road surface and also permit theraising of the suction head 23.

At the forward end of the vehicle, there is preferably provided a fender33 which is arranged diagonally across the vehicle'so as to force largeobjects to one side ofthe same and prevent engagement thereof by thehood. Adjacent the rear of the ve hicle immediately in front of the hoodis a scraper 34 normally raised from the ground by means of a spring 35and actuated by a connecting rod 36 and lever 37 so as to be broughtinto engagement with the road surface for loosening the dirt thereon.4The body 7 is preferably provided with an ex. haust opening 38 which 1scontrolled by a sliding screen 39 having an operating handle 40 and thehood is provided with a reg'- istering opening..` The hood 1s preferablysupported upon suitable rollers 4:1, as shown. ln order to raise thehood and the suction head from the ground, there is pivoted to the frontof the vehicle adjacent the drivers seat a lever 42 connected to an arm43 on the suction head by means of a cable 44 which passes over pulleys45 mounted upon the top of the body 7. Y

It will be seen that the suction head is yheld adjacent the rear of lthchood so that any dirt exhausting through the screen 39 and falling inthe rear of the 'suction head will be thereby picked up again andcarried into the dust chamber 9. The hood is of such size and materialof such quality as to permit the eXhaustromthe blower to read'- ilyescape withoutplacing any strain thereon and some air is filteredthrough the can` vas fabric of the hood, as will be readily understood.

What is claimed is 1. yIn a street cleaner, a truck, a closed receptaclemounted thereon, a suction pump arranged to discharge in the receptacle,said receptacle having a screened exhaust opening, a suction headconnected to the pump anda hood surrounding the suction head andcovering the exhaust opening, means for supporting the hood upon theground, and means to resiliently hold the same in engagement with theground.

2. In a street cleaner,l a truck, a vclosed body mounted thereon andhaving an exhaust opening, a partition dividing the body into separatecompartments, alsuction pump arranged in one compartment, means fordriving said suction pump, a suction head connected to lthe pump, a hoodsurrounding and connected to the suction head, means for supporting thehood upon the ground, means for resiliently holding the hood inengagement with the ground, and means for raising the head and hoodagainst said holding means.

In testimony whereof we alix4 oui` signatures in presence of twowitnesses.
